Transformers: Armada
The Starscream of the Transformers: Armada (Micron Legend in Japan) universe was notably similar yet different from his G1 predecessor. Like him, this incarnation of Starscream loathed his commander, Megatron, but not out of any desire to take command of the Decepticons – simply because of the sheer mistreatment and contempt Megatron heaped upon him. Another notable difference between Armada Starscream and his G1 predecessor was that this Starscream was a formidable warrior and a more serious character, never shying away from battle even when the odds were against him, while the G1 incarnation was rather faint-hearted. He possessed a rivalry with Hot Shot and later information would credit him with the severing of the Autobot Red Alert's hand. He also possessed a samurai-like sense of warrior's honor and he transforms into what resembles a Sukhoi Su-35.
It is often thought that the inspiration for his character came from the Beast Wars-era MaximalDinobot, who also defected from his initial faction, the Predacons, out of contempt for his universe's Megatron, possessed a code of honor and died a hero while gaining redemption.
In his original body, Starscream transformed into a jet, armed with twin null laser cannons activated by his partner Mini-Con, Swindle (Grid in the Japanese version). In robot mode, his left wing transforms into an energised sword blade, which he wields expertly (at one point, managing to outduel Hot Shot who was using the Star Saber at the time).
Starscream originally came to Earth as part of Megatron's expedition to gain the power of the Mini-Cons alongside Demolishor and Cyclonus. However, Starscream's frustration over having been made the last of the Decepticons to gain his partner Mini-Con led him to be manipulated by Sideways into battling with Megatron, which he promptly lost. A short time later, Starscream was given ownership of the Star Saber as part of a scheme by Thrust to make him the patsy in his plan to steal the Requiem Blaster from the Autobots. This led to him being abandoned on the battlefield. Surviving to return to the Decepticon base, Starscream went on a rampage with the sword and disowned the Decepticons, siding up with the wary Autobots, not out of any desire to do good, but out of sheer hatred for Megatron. After a clash with Hot Shot and a trip to Mars with Jetfire, Starscream befriended the Autobots' human allies, particularly Alexis, and then gave the Autobots access to the Decepticon base, resulting in a raid that freed all the captive Mini-Cons. Starscream's defection was not without difficulty however; he constantly clashed with the Autobots over morals and battle strategies. Nonetheless, he proved to be a capable Autobot. However, Thrust (himself being manipulated by Sideways) then toyed with Starscream, planting seeds of doubt in his mind. This eventually caused him to steal the Skyboom Shield from the Autobots and return to the Decepticon fold, giving the Decepticons possession of all three Mini-Con weapons.
Subsequently, Starscream was among the Transformers injured battling Nemesis Prime, and who then received power boosts from their Mini-Cons. Starscream gained a new, blue coloration that he commented made him look like his contemporary, Thundercracker. Returning to Cybertron, Starscream pursued Thrust into the depths of the planet when the turncoat tactician revealed his treachery by stealing the Requiem Blaster and Skyboom Shield. Starscream took a fatal shot from the Requiem Blaster as he battled Thrust in the subterranean tunnels, but the Mini-Con High Wire used his powers to restructure the timeline, saving Starscream. Thrust escaped and delivered the weapons to Sideways and his master, Unicron, presently disguised as Cybertron's moon. Following Thrust through a warp gate and briefly reuniting with Alexis, Starscream entered the belly of the beast along with Hot Shot and Wheeljack, but the unlikely trio were stymied by Unicron's internal defenses and failed to stop Sideways from using the weapons to begin Unicron's reactivation. Galvatron (the renamed Megatron after the Mini-con power boost) was unwilling to acknowledge Unicron's threat, however, dismissing it as an Autobot trick. Starscream, however, knew the threat was real, and that only united under a true leader like Optimus Prime – whose strength of character and nobility had touched Starscream during his time with the Autobots – could the Transformers hope to stop him. Unwilling to betray his leader, Starscream decided on a new course of action. To show Galvatron the error of his ways, he challenged him to a duel in which he allowed Galvatron to run him through with the Star Saber, and then turned his firepower on Unicron, right after he demands Galvatron to join forces with Optimus Prime to stop Unicron. Unicron promptly obliterated him, much to the shock of both Galvatron and Optimus Prime. It was then Galvatron realized that the danger of Unicron was real. Upon realizing Starscream's reasons of his rebellion, Galvatron became more than willing to have the Decepticons form an alliance with Optimus and the Autobots to stop Unicron for good. Other than that, Galvatron develops a newfound respect for Starscream, despite his treason (although it was for the same good reasons), and develops a hatred against Unicron for killing Starscream. Starsceam's final action saved everyone and made him the only incarnation of Starscream in the various Transformers universes with a good heart in the end. Alexis, who Starscream had formed a close bond with, was deeply affected by his death. Starscream, or a version thereof, was briefly seen only once more, in a dream that Galvatron had while he was temporarily absorbed into Unicron's mind.
